(
Brief data summary
and
scan listing
)
EM101C, C-band e-VLBI run on 2013 June 18. Participating telescopes were Jodrell Bank, Westerbork, Effelsberg, Onsala, Medicina, Noto, Torun, Yebes and Hartebeesthoek. Medicina observed at 512 Mbps (but used 1-bit sampling to recover the full bandwidth).
The target and check sources were phase referenced to J1743-0350.
The EVN reliability indicator (ERI) for this experiment was
ERI = 1.00 . ERI* = 1.00 .
(Ef=1, Jb2=1, Ys=1, On=1, Mc=1, Nt=1, Tr=1, Wb=1, Hh=1)
Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations.
plots of the uncalibrated amplitude and phase
against time
Comments.
Full-experiment on Ef-* baselines, no calibration applied. A 1.0-minute plot-averaging was used.
Plots of the uncalibrated amplitude and phase
against frequency channel
Comments.
Scalar averaged Ef-* baselines, each scan plotted separately. No calibration applied yet.
The uncalibrated amplitude and phase of the crosshand
correlations against frequency channel
Comments.
Scalar averaged Ef-* baselines for LR, each scan plotted separately. No calibration applied yet.
TSYS against time
Comments.
TY1 table.
Telescope sensitivities
from the a priori TSYS and Gain
curves (the square of this number gives the antenna noise (SEFD) in Jy - the
smaller the better).
Comments.
Gain amplitude from CL2 table.
Fringe-fit phase solutions
(including Parallactic
Angle correction).
Comments.
CL3 station phase solutions -- CL3 = CL2+SN2, thus also includes the initial amplitude/parallactic angle calibration from CL2 and the fringe solutions from SN2.
Fringe-fit delay solutions
Comments.
SN2 station delay solutions for the fringed sources. Proper solutions found at all stations.
Fringe-fit rate solutions
Comments.
SN2 station rate solutions.
Telescope bandpasses
Comments.
Bandpass table 1.
Calibrated amplitude and phase against time
(a
priori amplitude calibration and fringe-fit solutions applied).
Comments.
Full-experiment for Ef-* baselines, calibrated with CL3.
Calibrated amplitude and phase against frequency
channel
Comments.
Ef-* baselines calibrated with CL3 and BP1.
